TROLLEY.

Specicaton of Letters Patent.

Patented Sept. 12, 1905.

Application filed February 4, 1905. Serial No. 244,111.

To all whom it 1v1/ty concern:

Be it known that I, WILLIAM S. TIoHENoR, a citizen of the United States,and a resident of Owensville, in the county of Gibson and State ofIndiana, have invented a new and Improved Trolley. of which thefollowing is a full, clear, and exact description.

This invention relates to improvements in trolleys for overheadelectric-railway systems, the object being to provide a trolley ofsimple and inexpensive construction and having shaft-bearings that arepractically dirt and dust proof.

Other objects of the invention will appear in the general description.

I will describe a trolley embodying mv invention and then point out thenovel features in the appended claims. l n

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

` Figure 1 is a side elevation of a trolley embodying my invention. Fig.2 is a section on the line 2 2 of Fig. 1, and Fig. 3 is a sectionon theline 3 3 of Fig. 2.

Referring to the drawings, 5 designates the trolley-harp removablysecured in openings, in the members of which are bearing-boxes 6 for thetubular shaft 7, on which the trolley 8 is secured, as here shown bymeans of a lag-screw 9. The boxes 6 have removable ends, and they aredetachably connected to the members of the harp. As a means forattaching the bearing-boxes to the harp they are provided with webportions 10, which engage in slots formed in the harp members tocommunicate with openings, and passing through openings in said webportions at the opposite sides of the harp members are cotters 11. Thetubular shaft 7 has its bearings in antifriction-rollers 12, arranged inthe bearingboxes, and oil is supplied to the bearings from oil-cups 13.

The current is carried from the trolley 8 through the harp by brushes14, which engage around the hub of the trolley and are secured to theharp members by means of bolts 15. Also secured to the harp members atthe outer sides and by means of the bolts 15 are guard-plates 16, whichare engaged at their upper ends by means of a bolt 17 passing throughthe tubular shaft 7. These guard-plates will prevent the conductor-wirefrom engaging with the bearingboxes should the'trolley slip from thewire.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A trolley-harp having openings and slots in itsmembers, said slots communicating with the openings, bearing-boxes forengaging in the openings and having web portions for engaging in theslots, devices passing through said webs for holding the boxes in place,antifriction devices in the boxes, and a trolley having itsshaft-bearings onv said antifriction devices.

2. A trolley-harp, bearing-boxes arranged `WILLIAM S. TICHENOR.
